Problem with DecimalFormat

This code (which I didn't write) occasionally prints an error like 'price: 7.949999809265137java.lang.NumberFormatException: For input string: ".795E1795E1"'

Anyone know how this could happen?

Could you post an example that ALWAYS gets the error?
In other words, write some sample code that sets the value of price to cause the error. Then run that simple program and copy/paste all of the output here.

I hope nobody is using that code in real life; it is bad enough using double values for money, but float with its lower precision is even worse.

Besides, it is a very roundabout way of rounding a number to two decimal places.
 
I agree. Here's the link: http://aspose.com/file-tools
